Restriction on the antimatter amount in the early universe based on data on the interaction of antiprotons with 4He
Description
The cross section for 3He production in antiproton interaction with 4He has been measured at the LEAR accelerator of CERN at antiproton energies of 20, 50 and 180 MeV. An analysis of the obtained experimental results permits to impose the following restriction on the amount of antimatter in the eraly Universe (103 <t <= 1013 s) R=nsub(anti p)/nsub(p) <= (0.7-1.1)x10-3
